Benefits of technology

[0013]Thus, in an array substrate and a display device having the array substrate according to an exemplary embodiment, an area for forming an angle of about 45 degrees between an alignment direction of liquid crystals and a polarization axis thereof are significantly increased to substantiall

Problems solved by technology

Obtaining a wide viewing angle and a fast response time of the liquid crystal layer is an important issue in LCD technology.
However, the liquid crystals in a boundary area of domains of the multi-domain structure are insufficiently controlled, and textures are generated in the boundary area, thereby substantially decreasing light transmittance, causing a substantially deterioration of the display quality of the LCD.
In additio

Embodiment Construction

[0027]The invention will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like reference numerals refer to like elements throughout.

[0028]It will be understood that when an element is referred to as being “on” another element, it can be directly on the other element or intervening elements may be present therebetween. In contrast, when an element is referred to as being “directly on” another element, there are no intervening elements present. As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items.

[0029]It will be unde...

Abstract

An array substrate includes a first pixel electrode and a second pixel electrode. The first pixel electrode includes first branch electrode portions and second branch electrode portions. The first branch electrode portions are disposed in a first area of a unit pixel area and are substantially parallel to a first side of the unit pixel area. The second branch electrode portions are disposed in a second area of the unit pixel area and are substantially parallel to a second side of the unit pixel area. The second pixel electrode includes third branch electrode portions disposed between the first branch electrode portions and fourth branch electrode portions disposed between the second branch electrode portions.

Description

[0001]This application claims priority to Korean Patent Application No. 2009-12448, filed on Feb. 16, 2009, and all the benefits accruing therefrom under 35 U.S.C. §119, the contents of which in its entirety are herein incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to an array substrate and a display device having the array substrate. More particularly, the present invention relates to an array substrate having a substantially horizontal electric field and a display device having the array substrate.[0004]2. Description of the Related Art[0005]A liquid crystal display (“LCD”) device is a widely used type of flat panel display device. An LCD device typically includes two display substrates having electrodes, such as a pixel electrode and a common electrode, for generating an electric field disposed thereon, and a liquid crystal layer disposed between the two display substrates. When a voltage is applied to the e...
